SLIDE FASTENEB Application med December 3, 1938. Serial lo. 645,505.

This invention relates to the class of devices known as slide fasteners,in which cooperating fastener elements are engaged and disengaged bymeans of a slide operating over the same. Y

The objects of theinvention are to enable the slide being operated fromeither side of are attained by the novelfeatures of construction,combinations and relations of parts 2 hereinafter described, illustratedin the accompanying drawing and broadly covered in the claims.

In the drawing, one sim le practical embodiment of theinvention 1sillustrated, but

it is to be understood that the structure may Stringer appearing insection.

`be modified as regards this particular disclosure, all within the trueintent and broad scobpe of the invention.

ig. 1 in the drawing is a broken front or face vew of the fastener.

Fig. 2 is an edge view with the tape or Fig. 3 is a cross-sectional vlewas on substantially the plane of line 3--3 of Fig. 1.

Considering the structure in detail, the interengaging coupling orfastener elements are indicated at 5, carried by tapes or stringers 6,and adapted tobe engaged and disengaged by the Y shape slide 7.

Actuating means for the slide are shown provided in the form of a tab orpull 8, and Athis handle member is reversibly connected with the slide,so that it may be used equallyT -well at either side of the fastener. Inthe illustration, the reversible connection for the pull comprisesa loop9, extending over the crotchportion of the Y slide from one side to theother, the pull handle having an opening 10 therethrough receiving theloop andi enabling the pull to be freely turned over from one side tothe other of the slide.`

In addition to being operable from either side, the slide can be lockedin its positions of adjustment at either side of the fastener, byreversible locking -means, consisting in the present disclosure of thelugs or prongs 11, 12, projecting from opposite faces ofthe reversiblepull and adapted to enter'through the guide openings 13, 14,respectivelyI in t e opposite faces of the slide. l

In the position shown in tlie full lines in the several views, thelocking prong 11 projects through the opening 13, into engagementbetween adjacent fastener elements, thereby securing the slide in thisparticular position and it will be evident, that upon reversing thepull, that is! by turning it up over the loop 9, in Fig. 2, the otherlug v12 can be 'thrust through the bpening 14 in the opposite sidev ofthe slide into interlocking engagementI with the fastener elements.Hence, the slide can be operated and secured in its adjusted positionsat either side of the fastener.

For yieldingly retaining the combined handle and reversible lockingmember in its locking positions at opposite sides of the fas-l tener,special means are provided, consisting in the present disclosure of thespring tongues `15, 16, struck out from opposite faces of the pull anddesigned to snap under the lower ed e of the slide as indicatedparticularly in ig. 2. one serving as a spring retainer for the lockingmember at one side of the slide and the other as a spring retainer forthe locking member 'at the opposite side of the slide.

To guard the projecting locking lug which is not in service, specialguard projections 17, ma be turned up from the slide, as indi-y cated mFig. 2, and as shown at the rightl in Fig. 1, where one of these guardsis shown standing at one side of the outwardlyprojecting locking lug 12.

In order that the pull may be conveniently used at either side of theastener and particularly without slipping idly up and down in thereversing loo 9, -said loop may be formed with lateral'o sets asindicated at 18,v

Fig. 2, into which the pull will naturally seat as it is turned up fromthe locking poslk tion at either side of the slide, the broken lines atthe right in Fig. 2 indicating this relation in which the pull isrestrained or temporarily-retained in the position for best actuatingthe slide. These offsets may be undercut somewhat to leave projectingshoulders 19 at the entrances thereto, adapted to prevent the pullaccidently slipping out of position during the slide actuatingmovements. The offsets 18 in the reversin serve as guards for thelockingl ugs 11,12, which, in their projecting relations stand betweenthese offsets, and the guards 17.

What is claimed is: 1. In a slide fastener, the combination ofcooperating interengaging fastener elements and a slide for'lacing andunlacing the same, actuating means reversibly connected with saidslideand operable to shift the slide at either side of the fastener, lockingmeans operable by said actuating means at either side of the slide,whereby said slide may be shifted and secured in its osition ofadjustment at either side ofthe astener, said actuating means includin ahandle and said lockingv means inclu ing lugs projecting from theopposite faces of sald handle for cooperation with the fastener elementsin reversed vpositions of said handle at either side of the slide andsaid slide having guide openings in opposite sides of the same forreceiving and positioning said oppositely projecting locking lugs 1n thepositioning of the handle at opposite sides of the slide.

2. In a slide fastener, the combination of cooperating interengagingfastener elements and a slide for lacing and unlacing the same,actuating means reversibly connected with said slide and operable toshift the slide at either side of the fastener, locking means operableby said actuating means at either side of the slide,'whereby said slidemay be shifted and secured in its position of adjustment at either sideof the fastener and means for releasably retaining said actuating meansin the locking positions of the same at either side of the slide.

4 3.- In a slide fastener, the combination of cooperating interengagingfastener elements anda slide for lacing and unlacing the same, actuatingmeans reversibly connected with said slide and operable to shift theslide at either side of the fastener, locking means operable by saidactuating means at either side of the slide, whereby said slide may beshifted and secured in its position of adjustment at either side of thefastener, said locking means including parts projecting from thereversibly connected actuating means and guards on the Aopposite sidesof said slide for said projecting locking means.
